The movie doesn't show Elvis having any romantic relationships after his divorce from Priscilla, excluding his hook-ups that we assume to be insignificant to him (we don't know their names, and they disappear quickly). Elvis clearly isn't over Priscilla, telling her he will always love her years after their divorce.
In reality, Elvis had two long-term relationships after his divorce from Priscilla. He dated songwriter Lisa Thompson for four years and later dated Ginger Alden for nine months until his 1977 death. Elvis proposed two months into dating Alden, who told Express that Elvis was looking forward to "marriage, more children, serious films and his next tour" in his final days.
